TUF-LINE® Guide’s Choice is a hollow, spliceable micro-filament line. The hollow core design allows monofilament to be spliced into the braid for the strongest possible main line to leader connection. Guide’s Choice is a must for “top shotting” monofilament into the braid. Simply insert the end of the monofilament approximately two feet into the braid and use floss to whip the area where the mono enters the braid. Use for making wind on leaders or as a backing for top shotting with monofilament. Use up to 30 lb mono with 40 lb braid, up to 50lb mono with 60 lb braid, up to 100 lb mono with 80 lb braid and up to equivalent lb test mono with 130-, 150-, 200-, 300- and 500lb test braid
